Effect of axion-like particles on the spectrum of the extragalactic gamma-ray background
Yun-Feng Liang, Xing-Fu Zhang, Ji-Gui Cheng +3
Axion-like particles (ALPs) provide a feasible explanation for the observed lower TeV opacity of the Universe. If the anomaly TeV transparency is caused by ALPs, then the fluxes of…
Lorentz Invariance Violation Limits from the Spectral Lag Transition of GRB~190114C
Shen-Shi Du, Lin Lan, Jun-Jie Wei +8
The spectral lags of gamma-ray bursts (GRBs) have been viewed as the most promising probes of the possible violations of Lorentz invariance (LIV). However, these constraints usuall…
Revisiting the analysis of axion-like particles with the Fermi-LAT gamma-ray observation of NGC1275
Ji-Gui Cheng, Ya-Jun He, Yun-Feng Liang +2
In this work, we re-analyze the Fermi-LAT observation of NGC 1275 to search for axion-like particle (ALP) effects and constrain ALP parameters. Instead of fitting the observed spec…
Jet Properties of Compact Steep-Spectrum Sources and an Eddington-Ratio-Driven Unification Scheme of Jet Radiation in Active Galactic Nuclei
Jin Zhang, Hai-Ming Zhang, Ying-Ying Gan +3
Compact steep-spectrum sources (CSSs) likely represent a population of young radio-loud active galactic nuclei (AGNs) and have been identified as gamma-ray emitting sources. We pre…
Diversity of gamma-ray and Radio Variabilities of Bright Blazars and Implications for gamma-ray Emission Location
Hai-Ming Zhang, Zhen-Jie Wang, Jin Zhang +4
Violent multi-wavelength variabilities are observed in gamma-ray-selected blazars. We present an analysis of long-term light curves for eight bright blazars to explore the co-varia…
Leptonic or Hadronic Emission: X-Ray Radiation Mechanism of Large-scale Jet Knots in 3C 273
Zhen-Jie Wang, Jin Zhang, Xiao-Na Sun +1
A comprehensively theoretical analysis on the broadband spectral energy distributions (SEDs) of large-scale jet knots in 3C 273 is presented for revealing their X-ray radiation mec…
